That's exactly why they locked the door, preventing any outsider from entering.
"After that, screams kept coming from outside."
The middle-aged teacher spoke with some fear, "I guess those were other students from different classes...."
"There are too many students around here, some of them inevitably go out, and that's probably why those monsters temporarily spared us......"
There's a saying: In the face of danger, you don't have to run faster than a bear, you just need to be faster than your teammates.
This is a school, and it's full of easy prey students everywhere, so those monsters naturally don't bother attacking the classroom.
They probably consider those in the classroom as reserve food, not too late to kill them after finishing off the ones outside.
That's why they had narrowly escaped.
But everyone knew in their hearts that after a while, those monsters would definitely barge in.
By then, they still had nothing but a dead end to face.
"Thank you."
